Why it's free to use

  • Filed March 31, 1982 and granted January 10, 1984. A patent filed before June 8, 1995 lasts 17 years from grant or 20 from filing, whichever is longer, so its term ended March 31, 2002.
  • Any extension is capped at five years, so it can't still be in force.
  • We haven't checked its US family, and a later related patent could still be in force. We check US rights only.
